To all whom t may concern.'

Be it known that I, PI-IILIPP WIRTH, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful improvements in Filling-Faucets, of which the following is a specification.

This invention relates to a device for filling containers, such asv barrels and casks, and has particular application to an automatic faucet operable to cut off a supply of liquid or fluid when a predetermined quantity of the latter has been fed into the container.

In the present instance, it is my purpose to provide a filling faucet through which the liquid may pass, from a source of supply, into the container, and which faucet will operate .under fluid pressure, such as air, from within the container to automatically cut off the supply when the liquid has reached a certain height in the container. By my invention, the necessity of having an attendant carefully watch the filling operation to prevent the overflow, or spilling and consequent waste of the liquid, is obviated, while considerable time, as well as labor, may be saved where a large number of casks or barrels are to be filled, because a number of the faucets may be in use simultaneously on a corresponding number of barrels and all'under charge of one attendant, as each individual faucet, being automatic in its cut-off operation, will not require personal attention on the part of the operator to prevent overflow.

It is also my purpose to provide an automatically operating filling faucet of this type which will embody the desired features' of simplicity, efliciency, reliabilityand convenience, and which may be manufactured and marketed at a relatively low cost.

With the above recited objects and others of similar nature in view, my invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings,

Referring now to the accompanying drawings in detail, the letter A indicates conventionally a barrel, cask or other container, having the usual bung-hole c and within which the faucet is intended to be inserted.

My improved automatically operating cutoff faucet is indicated as an entirety by the letter B and embraces a casing 1 interiorly divided by the wall 2 into the valve chambers 3 and 4. Communicating with the valve chamber 4 is a hollow coupling head 5, to which may be attached a flexible hose, or other fluid conduit, shown at 6, and from which the liquid passes from a source of supply into the faucet, this hose being fas-- tened to the coupling head of any suitable coupling, such as is shown at 7. Preferably formed integral with and depending from the body of the casing 1, is the barrel 8 of the faucet, this barrel communicating through the valve passage-way 9 with the valve chamber 4. The upper portion 10 of the faucet barrel is tapered in form,

and merges into the straight or cylindrical section ll, which forms the lower end section of the barrel. The interior of the barrel is provided with a fiuid passage, in the present instance, an air conduit or passageway 12 which opens at its lower end through the wall of the cylindrical section l1 of the barrel, as shown at 12, and at its upper end communicates through the channel or by-pass 14 with the lower portion of the valve chamber 3. Within the valve chamber 4 is located a disk valve 15 having a bevclededge 16, so that the valve may seat against the correspondingly tapered wall 17 of the passage 9 between the chamber 4 and the barrel of the faucet, as will be readily understood, The stem 18 of the valve slides in the socket 19 of the screw cap 20, and which cap constitutes the top wall of the chamber 4. A suitable packing 21 may be employed to make the cap duid-tight when screwed in place. The interior of the valve chamber 3 is cylindrical in form and sliding therein is a cylindrical, hollow plunger 22 having a lower end wall 23 in the form of a perforated disk or head threaded into the end of the plunger, the perforations being shown at Likewise, the upper end wall of the plunger is shown at 26 and this wall is also perforated as at 27 and is formed with a hollow, central stud 28 projectingr through the opening 29 in the center of the screw cap 30, this latter cap forming the top wall of the chamber 3. A stem or handle 31 is threaded into the stud socket 28, so that the plunger may be lifted manually when desired, as hereinafter mentioned. A horizontal web 32 extends across the interior of the hollow plunger and is formed with a central opening 33. A cage is thus formed in the lower part of the plunger for the ball valve 34 which is adapted to be lifted by air pressure to close the passage 33, as will be hereinafter understood. The numeral 35 indicates a revoluble shaft finding bearing in the lower portion of the casing 1, the inner end of the shaft lying just below the passage-way 9 between the barrel of the faucet and the chamber 4, this end of the shaft carrying a collar 36 provided with a valve lifting cam 37 which is adapted to lift and support the valve disk 15 at certain times. On that intermediate portion of the shaft, which lies in alinement with the chamber 3, is a collar 38 carrying the plunger lifting stem 39, which is adapted to support the plunger in elevated position at predetermined times. The outer end of the rotating or rocking shaft 35 carries counterweighted arm 40, the coiuiterweight of the arm being practically in the form of a sphere and of heavy metal, such as is shown at 41. The shaft is also made fluidtight and held in position by suitable packing nuts and glands, as shown at 42. These packing nuts and glands 42 may be of any suitable and well known construction.

From the above description taken in connection with the'accompanying drawings, the construction and operation of my automatic filling faucet will be readily under stood. When it is to be used, the lower or cylindrical end of the faucet barrel is inserted in the bung-hole until the tapered section of the barrel wedges against the tapered wall of the bung-hole, and in this position, the air opening 13, leading to the passage l2, will communicate with the interior of the barrel. The operator may now grasp the stem 31. and lift the plunger 22 within the chamber 2, at the same time grasping the counterweight 41 and swinging the arm 40 upward to the position shown in full lines 1n Fiom 5. This will cause the rock shaft 35 to be turned, thus swinging the stem 39 upward within the chamber 3 and likewiseswinging the cam 37 upward, and consequently lifting the valve disk 15 from its seat, so as to open the passage 9 Vbetween the chamber 4 and the barrel of the faucet. The operator may now release his grasp upon the handle 31 and the plunger will settle down or drop back onto the stern 39, holding, or pinning, the stem in its elevated position, and consequently holding the counterweight 41 elevated and likewise insuring that the valve 15 will be held open by the cam 37, as the shaft 35 is thus held stationary. The liquid may now flow through the hose 6, coupling 5, chamber 4, passage 9 and the barrel of the faucet into the con tainer A. As the liquid continues to feed into the container', the air pressure within the latter is gradually increased as the liq' uid displaces the air, until when the container is substantially full, or until the level of the liquid has about reached the air hole 13, the pressure of air will be so great that as it is forced through the -air passage 12 and by pass 14 into the chamber 4, it will pass up through the ports or apertures 25 in the lower end wall of the plunger, and will. lift the ball valve 34, thus cutting olf, or closing, the opening ,'33 in the wall 32. Then this opening is thus plugged by the ball valve, the continued pressure of the air will force the plunger upwardly, just a sufficient distance to lift it off the end of the stem 39, which has been held elevated by the plunger, and the stem being thus released, the counterweight 4l will draw the arm 40 downward, thus rocking the shaft 35 and lowering the stem 39 and. also the cam 37, the downward movement of the latter al* lowing` the valve disk 15 to drop to its seat, thus closing the passage 9 between the chamber 4 and the barrel, and thereby shutting off the supply of liquid to the barrel. The faucet may then be removed, and the bung inserted in the barrel, and the faucet may then be used for filling other barrels, as will be obvious.

While I have herein mentioned air kas the pressure exerting medium, it will, of course, be understood that the valve will operate equally well under pressure of other fluids, such as a liquid for example; and while I have herein shown and described one particular embodiment of my invention, I wish it to be understood that I do not confine myself to all the precise details of construction herein set forth by way of illustration, as modification and variation may be made without departing from the spirit of the invention or exceeding the scope of the appended claims.
